Sang began her career at the age of eight, as Cheryl Gray, by singing on Australian radio[4] and entered and won talent contests.
[6][8] Teen magazine, Go-Set ran a poll in August for pop performers and Gray was voted third in the 'Top Girl Singer' category behind Lynne Randell and Bev Harrell.
In 1969, Sang travelled to the United Kingdom where Barry Gibb of the Bee Gees heard her singing and urged his manager, Robert Stigwood, to sign her.
[10] Sang's version – with Barry Gibb supplying backing vocals, guitar and producing – was released in August.
[13] She visited Barry Gibb in France whilst the Bee Gees were recording songs for the Saturday Night Fever soundtrack.
The single was co-produced by Barry with the Bee Gees' production team of Albhy Galuten and Karl Richardson.
[15][18] Determined to succeed on her own merits, Sang did not record another Gibb song to capitalise on her success, but chose a disco track, "You Keep Me Dancing", as her next single.
[6] In 1999, residing again in Melbourne, Sang made a short return to live performing, with her father Reg as guest vocalist.
